Yeah I take my L from the Arabic translation Sanji is clearly using Ifrit Jambe without the eyebrow reverse. It seems his genetic mode are always active. It makes no sense why they eyebrow flip is even a thing then. Right now Sanji is no where near Zoro and even after he gets CoC and even if he washes Killingham in one hit, he will still have performed worse than Zoro. I think its safe to say that Sanji << Zoro.
To all the Zoro fans I have argued with I am sorry - you have always been right Luffy and Zoro are way past Sanji. Its ironic that the moment where Sanji was supposed to get ACOC would be the thing which confirms he is way weaker than Zoro.
